Abstract
The utility model provides a generator stator fanning strip stamping die, including last mould and lower mould, locate the guide pillar between the upper and lower mould, set up respectively at the die of last mould downside and the terrace die of lower mould upside through the mounting, be equipped with removable strip groove drift, round hole drift, small circle hole drift, slotted hole drift greatly on its characterized in that die, be equipped with removable slotted hole die sleeve on the terrace die. Can only need to change drift and the slotted hole die sleeve that corresponds according to the concrete structure of the generator stator fanning strip of want punching press, can process out the generator stator fanning strip of correspondence, not only the investment economize, with low costs, work efficiency is high in addition, just can guarantee the machining precision, only uses the mould can many specifications of punching generator stator segmental punching.
Description
Technical field
The utility model relates to a kind of diel, and especially a kind of mould of fanning strip of generator stator of energy punching different size, belongs to generator parts manufacturing technology field.
Background technology
Stators and rotators is the important core parts of generator, motor, and stator segmental punching and rotor punching are the chief components of stator core and rotor core.0.5mm cold-reduced silicon sheet generally used by the material of stator segmental punching, punching dimensional accuracy IT8 ~ IT10, the accuracy of form and position≤0.1mm, due to precision having higher requirements, needs to use the large-scale precision composite die with accurately leading to complete punching.It can thus be appreciated that the Sheet Metal Forming Technology of punching and mould structure are the keys ensureing punching quality.As Fig. 4, Fig. 5, the stator segmental punching that Figure 6 shows that three kinds of specifications that same generator stator core uses, conventionally need to configure the punching that Third Mate's mould just can complete these three kinds of specification stator sector pieces, not only time-consuming, take a lot of work, but also to production cost be increased, also affect operating efficiency during punching, be therefore necessary to be improved prior art.
Summary of the invention
The purpose of this utility model is that providing a kind of only uses one pair of mould with regard to the mould of the multiple different size fanning strip of energy punching.
The utility model is completed by following technical proposal: a kind of fanning strip of generator stator diel, comprise upper die and lower die, be located at the guide pillar between upper and lower mould, the die on the downside of patrix and the punch on the upside of counterdie is separately positioned on by fixture, it is characterized in that die is provided with removable strip slot drift, big hole drift, small sircle hole drift, slotted eye drift, punch is provided with removable slotted eye die sleeve, to change as required wherein after one or more drifts, the different fanning strip of generator stator required can be stamped out.
Described strip slot drift, big hole drift, small sircle hole drift, slotted eye drift are bonded in the nibs of the fixture corresponding with die, to be convenient for changing while fixing.
Described slotted eye die sleeve is placed in slotted eye corresponding to punch, the tapped through hole that this slotted eye is corresponding with on counterdie is communicated with, and threaded top post is provided with below slotted eye, to make threaded top post screw out and be convenient for changing slotted eye die sleeve as required downwards, or upwards screw and fixed support slotted eye die sleeve.
Described punch is put together by three pieces of punch, is provided with split groove between the punch of split between two, to facilitate accurate split.
The utility model has following advantages and effect: adopt such scheme, can according to the concrete structure of the fanning strip of generator stator of wanted punching press, only need change corresponding drift and slotted eye die sleeve, corresponding fanning strip of generator stator can be processed, not only reduced investment, cost are low, and operating efficiency is high, and can machining accuracy be ensured, only use a mould can punching many specifications generator unit stator segmental punching.
